ذِكْرُ الْإِخْبَارِ عَنِ اسْمِ الْمَلَكَيْنِ اللَّذَيْنِ يَسْأَلَانِ النَّاسَ فِي قُبُورِهِمْ، ثَبَّتَنَا اللَّهُ بِتَفَضُّلِهِ لِسُؤَالِهِمَا فِي ذَلِكَ الْوَقْتِ
The Messenger of Allah said: "When the deceased - or he said when one of you - is buried, two angels, black and blue (eyed_ come to him. One of them is called Al-Munkar, and the other An-Nakir. They say: 'What did you used to say about this man?' So he says what he was saying (before death) 'He is Allah's slave and His Messenger. I testify that none has the right to be worshipped but Allah and that Muhammad is His slave and His Messenger.' So they say: 'We knew that you would say this.' Then his grave is expanded to seventy by seventy cubits, then it is illuminated for him. Then it is said to him: 'Sleep.' So he said: 'Can I return to my family to inform them?' They say: 'Sleep as a newlywed, whom none awakens but the dearest of his family.' Until Allah resurrects him from his resting place.""If he was a hypocrite he would say: 'I heard people saying something, so I said the same; I do not know.' So they said: 'We knew you would say that.' So the earth is told: 'Constrict him.' So it constricts around him, squeezing his ribs together. He continues being punished like that until Allah resurrects him from his resting place." (Using translation from Tirmidhī 1071)
قَالَ رَسُولُ اللَّهِ ﷺ «إِذَا قُبِرَ أَحَدُكُمْ أَوِ الْإِنْسَانُ أَتَاهُ مَلَكَانِ أَسْوَدَانِ أَزْرَقَانِ يُقَالُ لِأَحَدِهِمَا الْمُنْكَرُ وَالْآخَرُ النَّكِيرُ فَيَقُولَانِ لَهُ مَا كُنْتَ تَقُولُ فِي هَذَا الرَّجُلِ مُحَمَّدٍ؟ فَهُوَ قَائِلٌ مَا كَانَ يَقُولُ فَإِنْ كَانَ مُؤْمِنًا قَالَ هُوَ عَبْدُ اللَّهِ وَرَسُولُهُ أَشْهَدُ أَنْ لَا إِلَهَ إِلَّا اللَّهُ وَأَنَّ مُحَمَّدًا عَبْدُهُ وَرَسُولُهُ فَيَقُولَانِ لَهُ إِنْ كُنَّا لِنَعْلَمُ إِنَّكَ لَتَقُولُ ذَلِكَ ثُمَّ يَفْسَحُ لَهُ فِي قَبْرِهِ سَبْعُونَ ذِرَاعًا فِي سَبْعِينَ ذِرَاعًا وَيُنَوَّرُ لَهُ فِيهِ فَيُقَالُ لَهُ نَمْ فَيَنَامُ كَنَوْمَةِ الْعَرُوسِ الَّذِي لَا يُوقِظُهُ إِلَّا أَحَبُّ أَهْلِهِ إِلَيْهِ حَتَّى يَبْعَثَهُ اللَّهُ مِنْ مَضْجَعِهِ ذَلِكَ وَإِنْ كَانَ مُنَافِقًا قَالَ لَا أَدْرِي كُنْتُ أَسْمَعُ النَّاسَ يَقُولُونَ شَيْئًا فَكُنْتُ أَقُولُهُ فَيَقُولَانِ لَهُ إِنْ كُنَّا لَنَعْلَمُ أَنَّكَ تَقُولُ ذَلِكَ ثُمَّ يُقَالُ لِلْأَرْضِ الْتَئِمِي عَلَيْهِ فَتَلْتَئِمُ عَلَيْهِ حَتَّى تَخْتَلِفَ فِيهَا أَضْلَاعُهُ فَلَا يَزَالُ مُعَذَّبًا حَتَّى يَبْعَثَهُ اللَّهُ مِنْ مَضْجَعِهِ ذَلِكَ»
